Children in years past have always practiced their basic mathematics by using flash Cartes. This learning methodology is highly effective in sharpening children's computational capacity but lacks dynamic feedback. Flash Math duplicates the positive aspect of flash Cartes and provides dynamic feedback. Also, Flash Math scales problems according to children's proficiency so that they are not frustrated by difficult problems or unchallenged by less intricate equations. The problems presented are for children in grades first through third in a standard US school curriculum.
